Nium

Making green ammonia for fertilizer and energy transport

First Investment: 2023

Ammonia (NH₃) carries both the nitrogen needed to fertilize the world’s crops and the hydrogen needed for clean fuel, but the traditional Haber-Bosch process for making ammonia requires huge amounts of energy and spits out millions of tons of CO₂ annually. The patent-pending nanotechnology built into Nium’s small-scale reactors synthesizes ammonia at low temperature and low pressure, offering a source of green, on-demand ammonia for farming and the hydrogen economy.
